Place the XLR8 over the visual centers in the back of the head (occiput per se) and/or the laser can directly be used around the eye orbit. Unncessary to lpace laser directly of the eyelid to get benefits. The clinician may choose to place the #2 head over the nerve root (located using the myotome /dermatome chart) or the organ involved (using the Merrick chart).
There are two key forms of Nystagmus: pathological and physiological, with variations within each type. Nystagmus may be caused by food allergies or allergies to toxins, environment, nutritional deficiency impairing nervous system; such as a lack of inhibitory neurotransmitters etc. Also consider congenital, central nervous system disorders, toxicity, or medication side effects. If an eye muscle is torn due to trauma that is a surgical correction. If the muscle is weak due to a nerve trauma (such as a grade 3 muscle weakness ortho test) laser therapy works great to turn on as you see with standard myotome testing.
I have treated numerous cases of nystagmus with very good success. First take a history and identify causative factors listed above; if any remove the inhibitor such as recent change or added medication when symptoms started. The correction with Erchonia laser is to reset the C.N. for vision. Specifically, CN III, IV and VI. with both eyes and cover one eye; one at a time and perform Muscle Response Testing to identify dysfunctional muscle / nerve relationship.
